I have tested my phone (Pixel 5) with and without Tesla app in the background. I even reboot my phone with no apps in background to be sure. I can confirm that it makes NO difference, at least for my phone. It worked fine either way as the car key.
Had the same problem with my pixel 5a. The Tesla service guy spent 2 hours and final figured out that the default BT version on the phone (1.5) needs to be changed to 1.6. you need to be in developer mode to make the change.

I have the Pixel 4 and had no issue like that. Is it because the 5a shipped with an out of date BT setting? Or is it because my M3 is still sitting on an old firmware version 2021.3.106.5?

My Bluetooth version is 4.2, and my Googling tells me it can't be changed. Are we talking about different things?

That sounds like the AVRCP (Audio/Video Remote Control Profile) Bluetooth developer option. My Pixel 2 defaults to 1.4 and my Pixel 5 defaults to 1.5, both work properly as keys.
